Based on some reading, and this thread pvd , vtu , vti files with vtk wasm
I decided to try and Start trame in a sub process. When I do file open, it starts trame with the appropriate file. When I open a new file, it shuts down the process and starts the server up again. I wanted to use.Pywebview and put trame in an i frame. However, I can’t really do anything with this type of process because I can’t get anything to render on the screen except for the VUEUI. There is no geometry. When I refresh the window, I get some wslink errors. When I start up my app straight from the app script, everything is fine. I really don’t want to pull paraview into my install. I decided to go the separate process route because of possible sync issues with the actors in the mappers in VTK. Wasm.
